Customer ratings and reviews for 8 Cell Battery 4.4Hr

Rated 1 out of 5Â by KennyRay Battery only last 2hrs
The laptop, with all power saving features enabled, does not come close to 4.4 hrs of runtime.
Normal runtime, full charged to 10% left, is actully 2.0 hrs. My 5 year old original battery will last that long. Guess I wasted my $140.00

Rated 1 out of 5Â by FirsttimeHPuser Not Impressed
I thought that HP was reputable for having great products. I have used other brands and was so not impressed with them. I decided to give HP a try. My first HP computer and let me tell you the battery last maybe an hour at best. I am well aware of not to leave the computer connected to the AC charger, because it lowers the life of the existing battery. In addition, you won't be able to use your computer without it being connected to the AC adapter. But, I am so disappointed with the performance of this battery. I feel as though my computer constantly lives only when it's connected to a AC charger. I will do my research before I buy another HP computer.

Rated 1 out of 5Â by sm73 Poor Battery Life
Use the battery in my pavilion DV7 which is plugged in 95% of the time. Two batteries died in about 2 years. When the battery needs to be replaced, the DV7 apparently draws from the rapidly dying battery rather than the attached power supply. Net result is the computer is usable for minutes, then dies when the battery is exhausted (even with the power supply attached). I used the minutes to update bios and reinstall Micorsoft ACPI Compliant Control Method in device manager to no avail. I have used Dell and IBM (now Levono) laptops for years where the computer works with almost dead batteries so long as power supply is attached. Seems like a poor design by HP to me. At least they could offer a better battery to delay this conundrum for a few years.

Rated 3 out of 5Â by EricHP It is working
The new battery is working but it is more like good for 2.5 hours and not 4.4 hours as advertised, then when the battery is used instead of the plugin, the luminosity of the screen is barely enough for my old age eyes.
I'm glad I bought that battery at 40% discount because it is not worth the whole price.

Rated 4 out of 5Â by Larsen113 Okay so far; hope it lasts years.
From my experience and significant study of others' reviews it appears that this battery's longevity can vary immensely depending on use and care. Note that this is a lithium-ion battery and should be used very,very differently from a nickel-cadmium battery. I have some little concern because my HP Pavilion laptop still seems to be running somewhat warm. I hope I did no damage by mis-using the discarded battery in its old age. Emphasized guidelines for ideal use and care important for this particular battery could save a lot of difficulty.

Rated 4 out of 5Â by Reddog16 Battery was easy to order and fit in the laptop
I found the battery easily on your website. It was on sale so I got a good price. It was delivered to my house in a timely fashion.
